Horizontal Projectiles

A cannon is fired horizontally from a 5.0 m tall tower. How much time will it take until the projectile hits the ground?

• 0.5 s

• 1.0 s

• 2.0 s

• 5.0 s

A projectile is launched horizontally from the top of a 45.2-meter high cliff and lands a distance of 17.6 meters from the base of the cliff. Determine the magnitude of the launch velocity.

• 5.9 m/s

• 3 m/s

• 52.8 m/s

• 1.9 m/s

Why does a horizontally launched projectile have a parabolic trajectory?

• Because the horizontal and vertical motions are independent.

• Because the horizontal motion is affected by gravity.

• Because the vertical motion is constant.

• Because air resistance shapes the trajectory.

A projectile is launched horizontally from a 100-meter high platform. If the initial speed is doubled, how does the range change?

• The range is halved.

• The range remains the same.

• The range doubles.

• The range quadruples.

Which of the following statements is true about a horizontally launched projectile?

• The horizontal velocity changes due to gravity.

• The vertical velocity is constant.

• The horizontal velocity remains constant.

• The vertical acceleration is zero.

Explain why the horizontal component of velocity remains constant for a horizontally launched projectile.

• Because there is no horizontal acceleration acting on the projectile.

• Because the vertical motion affects the horizontal motion.

• Because air resistance increases the horizontal velocity.

• Because gravity acts in the horizontal direction.
